Derived from the Japanese term ou which is used mostly to describe members of the royalty. It is also used to refer to large sizes, both physically and figuratively.

'chan' is also a Japanese word used as a suffix for an admirable person.

ochan, in gender terms, refers a big/adult male connecting the meaning of ou with the male gender.

ochan in non-gender terms, can replace superlative adjectives pertaining to size both physically and figuratively.

ochan in family relations refers to a big brother while chichan refers to little brother

ochan in humor means big man - mostly referring to someone with a noticeable bulge and in extreme cases to his penis or balls.
